Ok, I've done Tren twice and have never done Deca. Whats everyones opinion on a better mass builder combined with Prop @ 100mg's ED?

Also, if I wanted to give Deca a go would it be ok to run Tren in the first 2-3 weeks while the Deca kicked in? Considering running it @ 400mg's a week with the Prop. Winny for the last 6 weeks.

Thanks
